Benefits of technology

The patent aims to offer a method for treating industrial cutting pieces that would significantly increase their lifespan.

Problems solved by technology

However, as stated in this article, such technology only allows doubling the number of coils which can be cut by the trimming knives which have been previously treated by the UCFT technology, which is not sufficient.

Embodiment Construction

[0040]The invention aims, notably, at proposing a treatment method, and associated equipment, intended for treating a cutting piece in order to increase its hardness and to increase substantially its lifetime.

[0041]In the following description it will be considered as an example that the cutting piece 2 is a rotary knife or wheel, such as the one illustrated in FIG. 2, and which can be used, for instance, in a side trimming equipment, such as side trimming equipment 1 illustrated in FIG. 1 and previously described on a pickling line or on a striping line. But the invention is not limited to this application. Indeed the invention concerns any type of cutting piece 2 as long as it comprises a cutting surface 5 with two opposite sides 6 separated by one or two cutting edges 7 depending whether it further comprises or not a binding face 8. So, a cutting piece 2 to treat may be a knife, scissors, a shear, a scythe or a blade, for instance.

[0042]As mentioned above, the invention proposes ...

Abstract

A method of treatment of a cutting piece (2) is provided. This method includes a first step in which a cutting surface (5) of this cutting piece (2) is subjected to shots thrown by an ultrasonic shot peening apparatus (10) to become a cutting surface (5) with shot impacts, and a second step in which the cutting surface (5) with shot impacts is grinded over a chosen thickness to become a treated cutting surface (5).

Description

[0001]The invention relates to a method of treatment of cutting pieces and to the associated equipment.[0002]The invention concerns any type of industrial cutting piece comprising at least one cutting edge. The invention applies more specifically to a cutting piece like rotary knives or wheels comprising a cutting surface with two opposite sides and one or two cutting edges depending whether it further comprises or not a face binding these opposite sides whose width makes possible to define two cutting edges.BACKGROUND[0003]Rotary knives or wheels are notably used in side trimming equipment intended for trimming at least one longitudinal side of a metal strip. An example of such a side trimming equipment 1 is schematically illustrated in FIG. 1. In the non-limiting example illustrated in FIG. 1, the side trimming equipment 1 comprises two pairs of rotary knives 2 intended for trimming simultaneously the two longitudinal sides 3 of a metal strip 4. For instance, the strip 4 may be ma...
